A year ago, Dietz Foods launched a yearlong advertising campaign for its canned tuna. Last year Dietz sold 12 million cans of tuna compared to the 10 million sold during the previous year, an increase directly attributable to new customers brought in by the campaign. Profits from the additional sales, however, were substantially less than the cost of the advertising campaign. Clearly, therefore, the campaign did nothing to further Dietz's economic interests.

追到这里问来了。。。。
我把题贴完整吧:
The technological conservatism of bicycle manaufacturers is a reflection of the kinds of demand they are trying to meet. The only cyclist seriously interested in innovation and willing to pay for it are bicycle racers. Therefore, innovation in bicycle technology is limited by what authorities will accept as standard for purpose of competition in bicycle races.
Which of following is an assumption made in drawing the conclusion above?
a) The market for cheap, traditional bicycle cannnot expand unless the market for high-performance competition bicycles expands.
b) High-performance bicycles are likely to be improved more as a result of technological innovations developed in small workshops than as a result of technological innovations developed in major manufacturing concerns.
c) Bicycle racers do not generate a strong demand for innovations that fall outside what is officially recoginized as standard for purpose of competition.
d) The technology conservatism of bicycle manufacturers results primarily from their desire to manufacturer a product that can be sold without being altered to suit different national markets.
e) The authorities who set standards for high-performance bicycle racing do not keep informed about innovative bicycle design.
就是一个“补桥”题:
前提和结论之间有Gap:
所有bicycle racers的demand都是standard for purpose of competition。
